AdBlue® (BlueHDi 
engines)
SCR system
Using a liquid called AdBlue® that contains 
urea, a catalytic converter turns up to 85% of 
the nitrogen oxides (NOx) into nitrogen and 
water, which are harmless to health and the 
environment. The AdBlue
® is contained in a 
special tank  holding about  
17 litres.
An alert system is triggered automatically once 
the reser ve level is reached: you can then drive 
for a further 1,500 miles (2,400 km) before the 
tank is empty.
If the estimated distance travelled by your 
vehicle between two ser vices is greater than 
12,500 miles (20,000 km), it will be necessary 
to top up the AdBlue. Once the AdBlue
® tank is empty, a system 
r
equired by regulations prevents starting 
of the engine.
If the SCR
 
system is faulty, the level of 
emissions from your vehicle will no longer 
meet the Euro 6 standard: your vehicle 
becomes polluting.
In the event of a confirmed fault with the 
SCR system, you must go to a CITROËN 
dealer or a qualified workshop as soon as 
possible: after travelling the distance of 
685 miles (1,100 km), a system preventing 
the engine starting will be triggered 
automatically.
In either case, a range indicator gives you 
the distance you can travel before the 
vehicle is immobilised. For more information on the Warning 
and indicator lamps
 and the associated 
alerts, refer to the corresponding section.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below 
around -11°C.
The SCR system includes a heater for the 
AdBlue
® tank, allowing you to continue 
driving in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be 
topped up as soon as the first alert is 
issued indicating that the reser ve level has 
been reached.
In order to ensure that the SCR system 
operates correctly:
-
 
U
se only AdBlue
® liquid that meets the 
ISO 22241 standard.
-
 
N
ever transfer AdBlue
® to another 
container: it would lose its purity.
-
 
N
ever dilute AdBlue
® with water.
To respect the environment and ensure 
compliance with the Euro 6 standard, without 
adversely affecting the per formance or fuel 
consumption of its Diesel engines, CITROËN 
has taken the decision to equip its vehicles 
with a system that combines SCR (Selective 
Catalytic Reduction) with a Diesel particle filter 
(DPF) for the treatment of exhaust gases.

150
You can obtain AdBlue® from a CITROËN 
dealer or a qualified workshop.
You can also visit a ser vice station 
equipped with AdBlue
® pumps specially 
designed for private vehicles (for those 
versions with access to the AdBlue
® tank 
via the fuel filler flap).
Never top up from an AdBlue
® dispenser 
reserved for heavy goods vehicles.
Recommendations on 
storage
AdBlue® freezes at about -11°C and 
deteriorates above 25°C. It should be stored in 
a cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept 
for at least a year.
If the additive has frozen, it can be used once it 
has completely thawed out.
Never keep containers or bottles of 
AdBlue
® in your vehicle.
Precautions in use
AdBlue® is a urea-based solution. This liquid is 
non-flammable, colourless and odourless (kept 
in a cool area).
In the event of contact with the skin, wash the 
affected area with soap and running water. In 
the event of contact with the eyes, immediately 
rinse the eyes with large amounts of water 
or with an eye wash solution for at least 
15
 
minutes. If a burning sensation or irritation 
persists, get medical attention.
If swallowed, immediately rinse the mouth with 
clean water and then drink plenty of water.
In certain conditions (high temperature, for 
example), the risk of releasing ammonia cannot 
be discounted: do not inhale the fluid. Ammonia 
vapour has an irritant effect on mucous 
membranes (eyes, nose and throat).
Keep AdBlue
® out of reach of children, in 
its original container or bottle.
Procedure
Before starting the top up procedure, ensure 
that the vehicle is parked on a flat and level 
sur face. In winter, check that the temperature of the 
vehicle is above -11°C. If not, in freezing 
weather, the AdBlue
® cannot be poured into the 
tank. Park your vehicle somewhere warmer for 
a few hours before topping up.
In the event of an AdBlue
® breakdown, 
confirmed by the message "Add AdBlue: 
Starting impossible", you must top up with 
at least 5 litres.
Never pour AdBlue
® into the Diesel fuel 
tank.
For the specifics associated with the 
access configuration for the AdBlue
® tank 
(via the boot or via the fuel filler flap), refer 
to the descriptions given in detail further 
on.
If any AdBlue
® is splashed, or if there are 
any spillages on the side of the body, rinse 
immediately with cold water or wipe with a 
damp cloth.
If the fluid has crystallised, clean it off 
using a sponge and hot water.

Important: in the event of a top-up after 
a breakdown because of a lack of 
AdBlue, you must wait around 5 minutes 
before switching on the ignition, without 
opening the driver's door, locking 
the vehicle, introducing the key into 
the ignition switch, or introducing 
the key of the 
 
K
 eyless Entr y and 
Star ting system into the passenger 
compartment .
Switch on the ignition, then wait for 10 
seconds before starting the engine.
Access to the AdBlue® tank 
via the boot
Filling the AdBlue® tank is an operation 
included in every routine ser vice on your 
vehicle by a CITROËN dealer or a qualified 
workshop.
Nevertheless, given the capacity of the tank, it 
may be necessary to top up the fluid between 
ser vices, as soon as an alert (warning lamps 
and a message) indicates it.
You are recommended to go to a CITROËN 
dealer or a qualified workshop.
If you intend to do the topping-up yourself, 
read the following procedure carefully.

topping-up. F

Maintenance and Warranty Guide.
Leather
Leather is a natural product. Appropriate 
regular care and cleaning is essential for its 
durability.
Refer to your vehicle's Maintenance and 
Warranty Guide for information on all the 
special precautions to observe.
Care of the stickers
These styling stickers are treated to give good 
resistance to ageing and tearing.
They have been designed to allow you to 
customise your vehicle's bodywork.
When using a high pressure jet wash, keep the 
end of the lance at least 30 centimetres from 
the stickers. For the care of the stickers in the rear door 
windows, we recommend the following:
-
 
U
 se a wide jet at a temperature of 
between 25°C and 40°C.
-  
W
 here possible, direct the jet at right 
angles to the stickers.

depending on country.
The triangle may be stowed under the boot 
carpet (in the storage box) or, depending on 
version, under the front passenger seat. Before leaving your vehicle to set up and 
install the triangle, switch on the hazard 
warning lamps and put on your high 
visibility vest.
Refer to the manufacturer's instructions on 
using the triangle.
Placing the triangle  
on the road
F Place the triangle behind the vehicle, as 
required by the legislation in force in your 
c o u nt r y.
The triangle is available as an accessory; 
contact a CITROËN dealer or a qualified 
workshop.
Temporary puncture 
repair kit
Scan the QR code on page 3 to view 
explanatory videos.
Comprising a compressor and a sealant 
cartridge, it allows the temporary repair  of 
a tyre so that you can drive to the nearest 
garage.
It is designed to repair most punctures which 
could affect the tyre, located on the tyre tread 
or shoulder.
Only  the 12 V socket at the front of 
the vehicle allows the compressor to be 
connected for long enough to repair or 
inflate the vehicle tyre.
The other 12 V sockets of the vehicle 
are not designed to be used with the 
compressor.
